I am facing a issue when try to remove a XSSF Table after creating one.
 
Here is my test case with manual print out result.
 
    Create 3 tables on a single sheet.
 
     [java] Create Table Name: /xl/tables/table1.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Create Table Name: /xl/tables/table2.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Create Table Name: /xl/tables/table3.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
 
Delete table2
 
    [java] Tables before deletion Name: /xl/tables/table1.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables before deletion Name: /xl/tables/table2.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables before deletion Name: /xl/tables/table3.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
 
     [java] Tables after deletion Name: /xl/tables/table1.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables after deletion Name: /xl/tables/table3.xml - Content Type: application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
 
Create a new table table and it throws exception as below
org.apache.poi.openxml4j.exceptions.PartAlreadyExistsException: A part with the name '/xl/tables/table3.xml' already exists : Packages shall not contain equivalent part names and package implementers shall neither create nor recognize packages with equivalent part names. [M1.12]
 
Looks like it tries to re-use table3.xml which already exists.
 
When I look into the code, this line.
XSSFSheet line 3971
int tableNumber = getPackagePart().getPackage().getPartsByContentType(XSSFRelation.TABLE.getContentType()).size() + 1;
